i am attempting to publish a customization project on an instance running on localhost (build 26.100.0175.4) on my dev box. if i publish from the CPE, it fails:
[2026-08-26 23:58:36.965] Validation finished successfully.
[2026-08-26 23:58:45.103] System.ApplicationException: The customization document has been changed after validation.
at Customization.CstManager.Publish(Int32 hashCode, ICustomizationLogger logger)
at PX.Web.Customization.Controls.Publish.DoPublish(Int32 hashCode, HttpResponse response)
[2026-08-26 23:58:45.111] An error has occurred. Please report this error to the technical support and attach the information provided above.
instance is running on a W11 box; no other users are connected, no IDE is running, only one instance of Edge is open, with the main browser open to SM204505, and the CPE window open attempting to publish. no other customization projects are published in the instance. the project contains no Modern UI items, and modern UI is not enabled on any screens in the instance. i’ve rebooted the workstation to insure no other processes are touching the files or database.
if i publish from SM204505, it successfully publishes.
interestingly, i get the same results when attempting to publish the same package on one of our test servers hosted somewhere in the sky…. publishing fails from CPE, but succeeds from SM204505.
thanks in advance for any suggestions.
